I tried to create a new certificate and got the following error:
Error: {“type”:“urn:ietf:params:acme:error:rateLimited”,“detail”:“Error creating new order :: too many certificates already issued for exact set of domains: mattermost.domain.com: see https://letsencrypt.org/docs/rate-limits/","status”:429}
Could this be the issue? Was MM trying to get the certificate multiple times and lock it self out?
